On Page 344, right after on page 343 at the very end it states "as a practical example of this, let's return to the idea of linking some text to the browser's Back button, via the window.history.back() method", the following code appears:
Please <span id=backSpan">go back</span> to the previous window and do what needs to be done.
window.onload = function() {
if (typeof window.print == 'function') {
var backSpan = document.getElementById('backSpan');
backSpan.onclick = function() {
window.print();
}
}
};
Shouldn't the window.print(); be replaced with "window.history.back()", given that page 343 at the end mentions using an example of window.history.back(), not of window.print(); ?
Thank you for your help in advance,
Alexander
